ES2DA 快恢复/高效率二极管(SMA)产品概述

一、产品概况

ES2DA 为 RUILON(瑞隆源)出品的独立式快恢复、高效率整流二极管,采用 SMA 封装。该器件在中等电流与中高电压整流与开关应用中提供良好的转换效率与开关特性,适合自动贴片生产线与典型功率电路使用。

主要参数:

  • 正向压降 Vf:0.95 V @ 2 A
  • 直流反向耐压 Vr:200 V
  • 连续整流电流 IF:2 A
  • 反向电流 IR:5 µA @ 200 V
  • 反向恢复时间 Trr:35 ns
  • 非重复峰值浪涌电流 Ifsm:50 A
  • 工作结温范围 Tj:-55 ℃ ~ +150 ℃
  • 封装:SMA(表面贴装)

二、产品特性与优势

  • 快恢复特性(Trr = 35 ns):在开关电源与高频整流场景中减少开关损耗与电磁干扰,比慢恢复整流更适用于中高速开关。
  • 低正向电压(0.95 V @2 A):降低导通损耗,提高整机效率,特别在持续整流或高占空比负载时收益明显。
  • 200 V 反向耐压与低漏电(5 µA):适合中等电压整流、离线电源和电源管理电路,对高压反向环境有良好稳定性。
  • 宽工作温度范围与 50 A 冲击能力:适应严苛工作环境并具备短时浪涌承受能力。

三、典型应用场景

  • 开关电源(SMPS)输出整流与续流二极管
  • 适配器、充电器整流桥或单只替换件
  • LED 驱动、家用电器电源模块
  • 电机驱动中的续流二极管与抑制回路
  • 逆变器与功率模块的保护整流

四、设计与选型建议

  • 若目标为最低导通损耗且电压要求较低,可优先考虑肖特基二极管;但在需要 200 V 以上耐压且避免肖特基高漏电的场合,ES2DA 在效率与耐压之间提供良好折衷。
  • 在高频大电流切换中,仍需关注反向恢复造成的尖峰电压与 EMI,必要时配合 RC 吸收或抑制网络。
  • 设计热管理时按工作结温与外壳散热能力留足裕量,SMA 封装对 PCB 散热依赖较大,建议增大铜箔面积并靠近热源布线。
  • 注意反向电流随温度上升显著增加,设计时留意在高温工况下的漏电影响。

五、封装与可靠性

SMA 表面贴装便于波峰/回流焊接与自动化装配。器件典型适配工业级温度范围,非重复峰值浪涌 50 A 满足常见启动或短时冲击场合。为保证长期可靠性,建议遵循厂商焊接曲线与 PCB 设计指南,并避免超过额定结温或频繁超出浪涌能力。

六、结论

ES2DA 是一款面向中等电流、中高电压场景的快恢复整流二极管,兼顾效率与耐压,适合开关电源、整流桥与续流等常见电源应用。合理的 PCB 散热设计与回路抑制措施将使其在实际电路中发挥最佳性能。若需更详细的电气曲线或封装尺寸,请咨询 RUILON(瑞隆源)产品资料或技术支持。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
